The fibroblast growth factor receptor substrate 2 (FRS2) is a key adaptor protein involved in signaling pathways mediated by fibroblast growth factor receptors (FGFRs) and other receptor tyrosine kinases (RTKs). Discovered in the 1990s, FRS2 acts as a docking protein that links activated FGFRs to downstream signaling cascades, including the RAS-MAPK and PI3K-AKT pathways, which regulate cell proliferation, differentiation, and survival. Structurally, FRS2 contains an N-terminal myristoylation site for membrane localization and multiple tyrosine phosphorylation sites that recruit signaling molecules like Grb2 and SOS upon receptor activation.
FRS2 antibodies are essential tools for studying its expression, post-translational modifications, and interactions in both physiological and pathological contexts. Researchers use these antibodies in techniques such as Western blotting, immunoprecipitation, and immunofluorescence to explore FRS2's role in development, tissue repair, and diseases like cancer. Dysregulation of FRS2 signaling has been implicated in tumorigenesis, particularly in cancers with amplified FGFR signaling, such as breast and lung cancers.
The development of FRS2-specific antibodies has advanced understanding of its dual regulatory roles—activating proliferative pathways while also modulating feedback mechanisms. These antibodies also aid in evaluating therapeutic responses to RTK inhibitors, making them valuable in both basic research and clinical applications.
